The Southern Ocean and Antarctic Circumpolar Current (ACC) play profound roles in Australian and global climate. However, we know little about how they will be affected by global warming. New velocity observations will tell us how the vertical mixing that contributes to the meridional overturning circulation, and ACC strength, change with the seasons and from year to year. The observations will also give us a better understanding of the oceanic and atmospheric processes that drive these changes. This new information will allow climate models to be better constrained so they can more accurately predict changes to Australian and global climate.

南大洋和南极绕极流（ACC）在澳大利亚和全球气候中发挥着深远的作用。 然而，我们对全球变暖将如何影响它们知之甚少。 新的速度观测结果将告诉我们，促进经向翻转环流的垂直混合以及 ACC 强度如何随季节和年份而变化。 这些观测还将让我们更好地了解推动这些变化的海洋和大气过程。 这些新信息将使气候模型得到更好的约束，以便它们能够更准确地预测澳大利亚和全球气候的变化。
